The best power banks and portable chargers for 2024

When you purchase through links on our site, we may earn an affiliate commission.

When you can’t find an outlet, a power bank or portable charger can come in handy. We have been testing batteries and updating this guide for over a year. In that time, I’ve seen power banks used for a variety of purposes, from the critical (keeping my phone charged while riding public transportation in an unfamiliar city) to the leisurely (recharging a tablet so I can continue doing the crossword without leaving the couch). 

So far, we’ve tested over two dozen banks to determine which are worthy, and these are currently the best power banks available.

The Best Power Banks

Anker PowerCore 10,000 mAk Redux

Capacity: 10,000mAh  |  Ports: 1 x USB-C, 1 x USB-A  |  Max output: 25W

While I adore my giant power banks, I also know from experience that the best power bank is the one you have with you, and big power banks are not well-suited to being carried around. This power bank is compact enough to fit in a pocket or bag while still providing adequate juice to your gadgets.

Charging takes 2.5 hours with USB-C and nearly 5 hours with USB-A. It is also a durable and dependable unit. I’ve had several of them in constant usage for a couple of years now, in jacket pockets, backpacks, and even the rear of my vehicle, and they’ve been used, mistreated, and bounced around from pillar to post, and they still work well.

This power bank has received numerous favorable online reviews, with many applauding its lightweight and small design.

Nitecore NB10000

Capacity: 10,000mAh  |  Ports: USB/USB-C Dual  |  Max output: 38.5W

The Nitecore NB10000 features 10,000 mAh of nominal capacity at full charge, carbon fiber frame and panels, USB-A and USB-C outputs, a single multi-functional button, blue and white LED indicators, and pass-through charging capability.

The outstanding feature of this power bank is its high capacity-to-weight ratio. For a weight that is little more than that of a typical 5,000 mAh battery pack, you get twice the power. That’s an attractive proposition for any backpacker who carries electronics on multiday trips.

Anker PowerCore 24K

Capacity: 24,000mAh  |  Ports: 2 x USB-C, 1 x USB-A  |  Max output: 140W

This beast can not only charge your smartphone, tablet, and headphones, but it can even power a USB-C laptop with its 140W output.

Another feature I enjoy about this power bank is the pass-through charging, which charges the power bank using one of the USB ports while using the other ports to charge devices. This useful “splitter” feature comes in handy when there aren’t enough power outlets. Connect the power bank to a charger linked into an outlet, then connect your gadgets to it — simple!

The OLED display, which provides at-a-glance information on capacity, power inputs, and outputs, however, distinguishes this power bank from the competition. This is a really excellent feature that makes small flickering LEDs look really old-school. I enjoy how the screen changes direction when I rotate the battery bank.

Ugreen 5000mAh Magnetic

Capacity: 5,000mAh  |  Ports: 1 x USB-C, 1 x wireless charging pad  |  Max output: 15W

This is one of the smallest power banks available, but that doesn’t mean it’s basic. Not only does this power bank have a battery capacity of 5,000mAh, but it also has a wireless charging pad and a USB-C port that can be used to charge other devices as well.

This bank also supports MagSafe wireless charging, which adds convenience by eliminating the need for iPhone owners to carry a cable. Finally, there is a trickle charge option that allows the bank to charge low-power devices like headphones or smartwatches without automatically shutting off, allowing you to listen to music and audiobooks for longer.

This power bank has received overwhelmingly excellent feedback, with owners praising its size and functionality. I’ve seen some reports about overheating, but I haven’t experienced it myself, and I suspect the owner has a thick case on their smartphone.

Anker MagGo 633

Capacity: 10,000mAh  |  Ports: 1 x USB-C and wireless charging |  Max output: 20W

Dimensions: 7.59 x 9.02 x 15.8 inches | Weight: 12 lb | Capacity: 56 ounces | Power: 1200 watts

The KitchenAid K400 blender has a classic design, with a large jar and simple dial controls. It has five numbered speed settings and three preset programs that alternate speeds to crush ice into snow, make slushy beverages, and blend uniformly textured smoothies. During our tests, we were impressed by how well the ribbed jar and asymmetrical blade combined to create a vortex that sucked in all of the ingredients, allowing them to blend thoroughly. There is a tamper included to push food into the blades, but we didn’t use it.

This blender has an affordable price for such an effective machine, and it comes in a variety of colors, ranging from pale green pistachio to KitchenAid’s signature bright red. However, it is quite heavy and tall, so do not expect it to fit neatly in a cabinet when not in use. It will most likely have to live on the countertop.
